Tella Web

Tella’s Reports feature empowers users to conveniently upload photos, videos, and audio recordings to their organization's Tella Web server. Its primary objective is to enhance the security of files collected on Tella by offering a simple method to back them up on a remote server. By having a copy of their files stored on the server, organizations ensure the preservation of important information even in the event of device seizure or destruction, and can organize it to use for research, advocacy, or accountability processes. For users on the ground, backing up their data to Tella Web means that they can delete the information from their phone and avoid potential repression. Implementing Tella Web involves three essential steps, which are thoroughly discussed in this section:

  • Install Tella Web: This step entails installing the Tella Web server and configuring the domain name to ensure its proper functioning.
  • Set up your project on your server: In this step, admins decide how to organize themselves to collect data, create “projects”, and set roles and permissions for their users.
  • Get people on the ground ready to start submitting reports: Users install Tella on their phones, whether it's an Android or iPhone device. They then connect to the Tella Web project and start collecting information, ensuring a smooth and efficient reporting process.

Install the server

This step consists of installing and configuring Tella Web on the server your organization will be using. This step needs to be completed by the person who is going to be responsible for the system administration (a developer or a system administrator). Technical instructions can be found on our Github.


Our team can offer support with the installation and answer any questions you may have. If you are planning to host a Tella Web server, contact us.


We offer a test server that you can use to test Tella Web before installing your own server. Contact us to get access to it.

Set up your project on your server

After you have your server installed and the first administrator user created, it’s time to set up the project or projects that the team on the field will share information to.


Take a look at this video tutorial for a demo of how to set up Tella Web.

Managing Projects

Tella Web allows you to create and manage projects, ensuring your reports are organized and accessible.

View all available projects

Click on the "Projects" button in the left navigation menu to access the "Projects" screen.

The "Projects" screen displays each existing project as a card.

Create a New Project

On the "Projects" screen, click the "Create project" button. A modal will appear, prompting you to name the new project. Enter the desired name for the project and click "Create." You will be redirected to the "Project settings" screen for the newly created project.

Open a Project

Open the "Projects" screen and click on the desired project card.

This will open the project, where you can access all the reports submitted to the project.

You can open, delete, or download reports based on your permissions within the project.

Configure projects’ settings

In the "Project settings" screen, you can customize various aspects of the project.

The screen is divided into three sections: General, Manage access, and Danger zone.

  • The "General" section allows you to rename the project, view project details, and modify the project's URL.
  • The "Danger zone" section provides options to delete the project, including all the reports within it.
  • The "Manage access" section enables you to add or remove users from the project.

User roles are general for the whole server. There are 4 roles: Admin, Editor, Viewer and Editor. Each user can only have a single role within a server. User creation is managed on the Users screen. Each one of these users can have access to one or more projects, which is configured on the Manage Access section of each project. Admins have access to all projects on the server.

Delete a Project

In the "Project settings" screen, scroll down to the "Danger zone" section.

Click on the "Delete project" option.

A modal will appear, warning you about the permanent deletion of the project and all its reports. To proceed with the deletion, enter the name of the project correctly (including the right case). Type "DELETE" (in capital letters) to confirm the deletion.

Once confirmed, the project and all its associated reports will be permanently deleted.

Configure the project URL

The project URL is automatically generated when the project is created. To edit the project URL, go to the "General" section in the "Project settings" screen and modify it accordingly. This URL is the one that reporters will use to connect to the project from their apps.

Managing Users

Only the server’s Admins have access to the "Users" screen on the left bar. This screen displays all the users who have access to this server.

Creating users

On the top bar, above the list of users, server's admin can click on the "Create user" button to create a new user in the server. Email, password, password-confirmation and role are required in order to create users.

Adminsan Admin has all permissions and can perform all actions on Reports and Users
Editorsan Editor can perform all actions related to Reports but no action related to Users
Viewersa Viewer has permission to log in Tella Web but can only view Reports. They cannot perform any editing or deleting.
Reportersa Reporter is a Tella user who has permission to submit Reports to the Tella Web server. A Reporter cannot log in Tella Web.


There are 3 entities for which permissions must be assigned:

  • Report
  • Project
  • User

On the password field, we added a password-security-meter to help admins and users to select secure passwords. We estimate password complexity using the zxcvbn library which considers:

  • Characters (more than 10)
  • Complexity (lowercase, uppercase, numbers, symbols)
  • No common patterns like dates, repeats (aaa), sequences (abcd), keyboard patterns (qwertyuiop)
  • No common passwords like names, cities, etc.

Only passwords rated as " Very strong" are allowed on Tella Web.

Managing access to projects

In the "Manage access" section of the "Project settings" screen, admins can assign existing users to the project. Click the "Add users" field. A dropdown menu will display all the users on the server. Scroll through the list or type to search for a user by username. Click on a user to add them as a pill in the "Add users" field. To remove a user from the list, click on the cross icon next to their pill. \ Click the "Add" button to save the changes and grant access to the project to the selected users. \


The full list of users who can submit reports to the project includes the users listed on this section plus all the server administrators

Get people on the ground ready to start submitting reports

The steps outlined below apply to both the Android and iOS versions of the Tella app. The reporting feature has been introduced in the following versions:

  • Tella Android v2.1.0 (152)
  • Tella iOS v1.1.0 (43)

To ensure that users have access to the reporting feature, please verify that your Tella app version is either of these versions or a more recent one.

Reports are not yet available on Tella-FOSS.


You can watch this video on how to configure and use Reports on the apps .

Connect to Tella Web Projects

  • Navigate to Settings ⚙️ > Servers > Add a server
  • Select "Tella Web" from the list of available server types.
  • Enter the login information (generated and provided by admins)
    • Project URL of your organization’s Tella Web server
    • Your Username and Password
  • Enable or disable advance features based on your use-case: auto-report, auto-delete and background submission.

Manage Tella Web Projects

  • In Settings ⚙️ > Servers > [Project name] > 3-dots you have the option to:
    • Edit: Opens an "edit server" screen where you can view the project's name, URL, and your username.
    • Delete: Deletes the server's URL, user credentials, and removes it from the Settings menu. All draft and submitted reports stored in your Tella app will also be deleted. This won’t delete any data that’s already submitted to the server.
    • Enable or disable auto-report, auto-delete and background submission.

Create a Manual Report

  • Once connected to at least one Tella Web project, a "Reports" card will appear in the "Connections" section of the home screen. Tap on this card to start creating reports.
  • The main reports screen allows navigation between the Drafts, Outbox, and Submitted tabs.
  • Tap the "New report" button at the bottom of the screen to create a new report.
    • On the "New report" screen you can fill in the report's details, including title, description, and optional attachments of photos, videos, and audio recordings.
    • If you are connected to multiple Tella Web projects, a selector will appear on the top of the screen.
  • Use the "Save draft" button (on the top right of the screen) to save the report as a draft without leaving the "New report" screen.
    • In order to be able to save as a draft, you need to enter the report’s title.
    • A toast message will appear on the screen to confirm the draft was saved.
  • The "Submit later" button saves the report to the Outbox for manual submission.
    • The outbox tab is often used when data collectors don’t have access to the internet or if the connection is not stable.
  • The “Submit” button sends the report to the Tella Web server immediately.
    • If submission fails due to connectivity issues, the report goes to the “Outbox tab”
    • If the report is submitted correctly, it goes to the “Submitted” tab

Draft Reports

  • On the "New report" screen, tap the "Save draft" button to save the report as a draft.
    • A toast message confirmation will be displayed, and you can continue working on the report without being redirected to the Draft tab.
  • If you try to exit a report without saving, a snackbar will appear to confirm you are sure to exit without saving the report.
  • In the Draft tab, you can view and manage draft reports. Open a draft report to finalize it and send it.
  • You can delete a draft report by going to More > Delete or by entering the report and tapping the Delete button.

Submit a Report

  • In a report, tap "Submit" to initiate the submission process.
  • You will be redirected to a summary screen displaying the upload progress for each element in the report (title, description, attachments).
  • A "Delete" button is available to stop the upload and delete the report.
  • If the report is actively uploading, a "Pause" button allows you to temporarily halt the upload, which can be resumed later using the "Resume" button.
  • Exiting a report doesn’t affect the upload status. If the report is actively uploading, the process continues.

Once something has been uploaded to Tella Web there is no way to delete a report on the server from the app. Deleting a submitted report will only delete the local version of it, not the information on the server. \


Deleting a report in the middle of submission will cancel the upload of the files that haven’t been uploaded yet, but submitted files and partially submitted files that are already on Tella Web won’t be deleted.


The Outbox contains reports that have been saved for submission. This could be:

  • Paused reports
  • Reports whose upload has been interrupted due to connectivity issues.

Submitted Reports

  • The Submitted tab displays reports that have been successfully submitted to the Tella Web server.
  • In the Submitted tab, you can view and review the submitted reports.

If the internet connection is interrupted, reports will go to the outbox tab and you'll need to manually resume them.

Advanced features


If auto-report is enabled, Tella will create and upload reports automatically whenever you take a photo, record a video, or capture an audio recording within the app. This ensures that your reports are seamlessly uploaded without the need for manual intervention. Files get upladed to the same auto-report if they are collected within the lapse of 30 minutes, which is specially useful on specific circumpstances, such as a demonstration.

Auto-report can be eabled from the Edit Connection screen.


auto-report can be enabled for only one project at the time


Tella offers an additional feature called auto-delete. When auto-report is enabled, you can enable auto-delete, which automatically removes reports and their associated files from your device after they have been successfully uploaded to the connected Tella Web project. This helps you manage your device's storage space and ensures that sensitive data is not unintentionally retained.

The auto-delete toggle button will appear below the auto-report toggle on the Edit Connection screen for the desired project.

Background Submission

Background submission allows you to continue the report submission process even if you switch to other tasks within the app or exit the Tella app entirely. This feature ensures that your reports are uploaded in the background, providing uninterrupted progress. Backround submission can work in combination to both Manual and Auto-reports, and can be ebabled on the Edit Connection screen for the desired project.

Once background submission is enabled, you can initiate the report submission process by tapping the "Submit" button in the "New report" screen or the "Resume" button in the summary screen. Regardless of your activities within Tella or whether you close the app, the upload process will continue without interruption. It will also work if auto-reports is enabled and you close the app after collecting the infromation.

During background submission, Tella extends the lock timeout to be able to transmit your data to Tella Web. To manually stop a background submission, tap the "Quick Exit" button on the Tella app's home screen.

If the submission is disrupted due to a weak internet connection or other factors, Tella will send the report to the Outbox tab and automatically restart the upload as soon as the phone regain an stable internet connection.
